Area Forecast Discussion National Weather Service Jackson MS 1014 AM CST Fri Dec 6 2019

UPDATE. Updated for morning discussion.

DISCUSSION.

A line of thunderstorms continues to progress through the region as an upper shortwave digs into the area. There has been enough elevated instability to result in a few strong thunderstorms across the region and this threat will continue over the next few hours along and east of the I-55 corridor. The main threat with any strong storms this morning will be small hail, gusty winds, and frequent lightning strikes. The threat will begin to diminish this afternoon as drier air continues to filter into the region from the west.

Prior discussion below:

Today through tonight: A compact shortwave trough will steadily move across the ArkLaMiss region in the near term. While instability and moisture are not impressive (MU CAPE ~ 400 j/kg, PW < 1.2 inches), there will be a several hour window for when cyclonic vorticity advection/lift will peak over northern portions of the forecast area this morning. This will support a convective system rooted above the cool boundary layer moving across north central MS, and per latest CAM guidance, localized rainfall amounts of one to two inches will be possible. Cooling cloud tops in latest IR loops and increasingly active radar/lightning trends support the heavier convective guidance solutions, but not expecting rainfall rates to raise flooding concerns at this point.

The surface low pressure system will weaken and move east of the ArkLaMiss region later today and tonight with a weak cool advection regime setting up. The result will be a lengthy duration of low clouds and light drizzle going through tonight. Temperatures will not cool all that much behind the departing system. /EC/

Saturday through Sunday night: Though much of the column will dry out behind today's quick moving system, a thin layer of low level moisture will persist in convergent cyclonic flow around the lingering surface low over the northeastern Gulf. Even with measurable rain likely out of the picture, drizzle will be possible through the morning Saturday, and somewhat dreary conditions are anticipated through the entire day. Unfortunately, the clouds may hang around for the entire weekend, as they increase again Sunday ahead of the next storm system. An upper jet streak will extend from the Southern Plains into the Ohio Valley ahead of a longwave upper trough by Sunday night. In increasing warm advection ahead of this system, a few sprinkles or light rain are possible, though more appreciable rainfall will hold off until the new work week.

Monday through Tuesday night: A surface low will drag a cold front into the Mid South by the daytime Monday, with rain chances beginning to increase. There is improving model agreement in the highest rain chances with this system occurring Monday night into Tuesday. Ahead of the front, weak instability may support isolated thunder on Monday night. Tuesday is currently looking like a rather nasty day, with the front clearing the area but postfrontal rain showers continuing as a cool northerly wind kicks in. There is a guidance trend toward rain chances ending more abruptly Tuesday evening into Tuesday night. Given poorer model agreement in recent previous runs, the official forecast was trended toward lower PoPs without removing them entirely for the overnight hours.

Wednesday and Thursday: A surface high will build in across most of the area on Wednesday. With the baroclinic zone lingering just off the coast, we can't entirely rule out an isolated shower across the southern portion of the forecast area, but overall guidance is trending drier during this time frame. /DL/

AVIATION. 12Z TAF discussion:

The weather will be rather poor for aviation interests this forecast period with widespread MVFR/IFR ceilings developing across the entire area as we go through the morning. A quick- moving upper level trough will bring a period of moderate to locally heavy SHRA/TSRA to especially the GLH/GWO/GTR corridor during the pre dawn and morning time frame. For sites farther south, less significant and shorter duration rainfall is expected. In the wake of the system later today into tonight, a weak cold advection pattern will bring IFR category stratus and perhaps some drizzle. /EC/

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
